Default Air Conditioner is WEAK

Dad bought a '15 GSW last month and he is telling me the A/C is weak with output temperature in the 50's. I noticed that my GSW A/C is under-whelming also but I didn't check the temperature

Is there something going on because these cars sat for two years that the air conditioners are weak? Dad's car is at the dealership and they told him it needed a little refrigerant. When we get it back he'll check the output temperature again and I will update the thread.

Any thoughts appreciated

They're not ice cold especially when sitting, that's for sure. I'm curious if your dad gets an improvement by having it serviced. I believe these compressors are designed with some fuel economy in mind, they have an interesting design to keep drag on the belt system down. Coupled with the fact that we only have ONE cooling fan may have that effect on how cold they can be. To me, it works great on the highway but in traffic it seems to not do as well.

I will let you know if we get any improvement on it. Did your car sit for two years?

My car sat for two years and has the same issue. I took it in to have it looked at on Thursday afternoon. Tech said it was low on R134; they recharged it. It is a little better but still not as cold as my ALH. Let me know what you find out.

Both of my '15s were purchased before the dieselgate, 50k and 60k miles on them. I don't think sitting for two years has anything to do with the issue

Mine has worked fine in the three weeks I've owned it, though I rarely use A/C if I don't need it (under 90F degrees and humidity under 75%). I was blipping it on last Thursday on a road trip each time I went down a hill for maybe 20 seconds or so and it cooled the car right down each time. No issues.

I do not use my AC too much ~~ (2 year old 2015 Golf (S) DSG TDi

In town I just flip it on then off in a few seconds.

On road, mostly off. If temp is over 90, a little more used.

With thermostat set on high, (COOL) even the lowest speed is way to cold

Only wish it had "zone temp control" like wife's RAV4 Limited.

Just now learning to adjust thermostat, and then set speed on lowest.

It sounds like mixed reviews on the A/C. I wonder if the people satisfied with the A/C have after market tinted windows?

Also, I wondered if sitting in the dealers lot for 2 years would hurt them because you are supposed to run the air periodically to lube the seals. Dried seals could lose refrigerant.

The car will be back on Tuesday and I will let you know what temperature Dad measures in the center vents.

Thanks everyone for the feedback. No consensus here yet, interesting

Keep in mind my unit was bought back in 2015 (July) and in normal service, albeit, low mileage use.

I do not have tint. But wish I did. Not for heat build up, but for better vision.

On a Summer daily run, it starts out in the garage; so no heat problems. After sitting in the "parking lot" (shopping, etc.) it's HOT.

Enter car, lower 2 windows, -- air on high, 10-20 seconds -- close windows, good to go.

Our '15 Passat blows cold enough to keep the car cool when set to 72 fan on low. So not sure if the sitting for 2 years is the issue.

The Alltrack seems to struggle a little more (could also be due to solar gain as no tint as of now), but it doesn't have climatronic. I'll try and get a temp prob reading.

In previous summers I've noticed the old Jetta was ice cold 40 or so but only if the RPMS were up above 1800 RPMs, and best on the highway. Around town it never really seemed to cool a heat soaked interior, you were comfortable but wouldn't call it cool.

Surprising but it still seems like there is no consensus on these air conditioners.

I had an appt Friday for a guy (with good on-line reviews) to come over and tint the windows on the GSW and he never showed up. This is my wife's car and we are doing it because her skin is sensitive to the sun. I have been concerned about limiting her vision since she works at night. How would it improve vision any more than a pair of sunglasses would? Sunglasses that you can't remove on a dark night?

yeah

Similar situation(s) here. I even wear gloves to protect my hands (skin)

Currantly weighing the cost vs night vision results with a tint job. If not good at night, would have to srape it off --

My wife's RAV4 is perfect, but I do not drive it. So there is no direct comparison.

On the 5 hour drive home yesterday the cars thermostat was saying it was 34C (93F) outside. The A/C was more than up to the task of keeping it comfortable inside. It doesn't blow ice cold like my '01 F-150 but it is more than adequate.

Thanks for posting this - I was about to start a similar thread! I had a 1.5 hour drive on the NY Thruway yesterday with five people in the car - 93F outside. The aircon could not keep up, although it was a bit better with the air recirculating rather than fresh air coming in. My GSW has been sitting 2 years - I've had it 4 weeks with about 1,000 miles so far. I'm bringing it in for 1,000 mile check up next weekend and will ask them to check refrigerant level.

Please let us know if they are able to improve the A/C and how they do it?
